If it has an immobilizer? You can find immobilizer bypasses on sale online, who knows if they work, or you can create your own and disable it yourself: https://www.youtube.com/watch?v=ispXq4EMrsY#t=24m45s https://www.youtube.com/watch?v=ispXq4EMrsY#t=24m45s https://github.com/fjvva/ecu-tool/wiki https://github.com/fjvva/ecu-tool/wiki (see also https://ioactive.com/pdfs/IOActive_Adventures_in_Automotive_Networks_and_Control_Units.pdf https://ioactive.com/pdfs/IOActive_Adventures_in_Automotive_... and http://opengarages.org/handbook/ebook/ http://opengarages.org/handbook/ebook/) So besides relaying the key, you can just hack via the CAN bus. There's also a trick to use a second ECU to bypass the immobilizer, but that's probably too time consuming. Many manufacturers (inc. Toyota) also allow bypassing immobilizers and other features using TechStream and a maintenance tool. If they claim you have to buy a new ECU if you lose your master keys, call bullshit: https://attachments.priuschat.com/attachment-files/2015/10/96213_T-SB-0043-14.pdf https://attachments.priuschat.com/attachment-files/2015/10/9...
